Abstract (en)

[origin: EP1550751A1] The monitoring procedure, for use on a loom on which the weft yarn is delivered by a feed drum (15) with an acceleration/deceleration compensator (27), includes a stage in which a first electrical actuator (17) of the drum is controlled by a signal representing the functioning of a second electrical actuator (22) driving the mobile member (20, 21) of the compensator. The second actuator is in the form of an electric servomotor controlled to give a constant torque, and the angular position of the drum is controlled so that the yarn tension after the yarn feeder (16) and compensator meet a predetermined value.
